Loop Duodenal Switch

The laparoscopic loop duodenal switch combines two bariatric surgeries.
First, a sleeve gastrectomy will be performed, which reduces the size
of the stomach to a thin strip (the “sleeve”). This restricts
the amount of food that can be consumed in one sitting and allows the
patient to feel fuller faster. For some patients, this alone is enough
to achieve the desired results, but for those that don’t the procedure
will be followed up at a later date with a duodenal switch.

The duodenal switch procedure reroutes food so that it bypasses a significant
portion of the small bowel, preventing your body from absorbing as much
fat and calories. This combination of two bariatric surgeries results
in dramatic weight loss results—typically 80 to 85% of excess weight.
It is only recommended for patients who need significant weight loss in
a short amount of time.

Is This Procedure Right for Me?

When used appropriately, the laparoscopic loop duodenal switch can significantly
improve a patient’s health and body fat percentage. Around 95% of
patients experience an improvement in quality of life and resolve obesity-related
health conditions. Mobility and energy are usually greatly improved as well.

Some benefits of this procedure include:

Rapid and significant weight loss

Can quickly resolve obesity-related health concerns

Weight loss results stick for most patients

Unlike Roux-en-Y gastric bypass surgery, this procedure does not have a
risk of dumping syndrome

This surgery makes very drastic changes to the stomach and digestive process.
It is also important to note that recipients of this procedure will need
be prepared to make lifestyle changes in order to accommodate the body’s
limited ability to absorb nutrients.

The following are possible disadvantages of this weight loss surgery:

Risk of nutritional deficiency

Possibility of developing an intolerance to sugar and fat

Changes in bowel habits may be permanent

May cause frequent gas pains

As with any surgical procedure, do not commit to anything before thoroughly
discussing the risks and benefits with your doctor and obtaining a solid
understanding of what the surgery involves.
